Some of you may have seen my previous post about my leaking radiator.
I got a new radiator and i am planning to replace it this weekend.

I noticed that the new radiator has two metal connectors on the bottom that i believe should connect to the Automatic transmission fluid lines.
This means that during the replacement procedure i'll have to drain some AT fluid. I am already concerned because i don't know how much AT fluid i will loose exactly in this process and how much i will have to add to the AT. How much AT fluid does the radiator hold?

Since i will be messing up with the AT fluid and since my AT fluid has more than 30k miles on it.... do you think that this may be a good time to do an AT fluid flush??

Like i said, my only concern is...how do i keep track of how much fluid i'll get out of the system and how much i add to bring it back to normal level. I'm sure i'll spil some.

Any ideas and suggestions are welcome.

Thank you!

 

I'd flush the tranny fluid, too.

 

lol..i replaced my rad a few weeks ago. I do have a 4th gen, but they're pretty similar i assume. You WILL spill some out. But as long as you tie up the 2 lines which connect to the rad, you won't spill much out.

It's up to you to do a tranny flush if you want to. You fluid should be ok. Be VERY CAREFUL not to crack those little prongs on the bottem of the rad when attaching the hoses back to your new rad. If i'm not mistaken, they are only aluminum and pretty fragile.

When i got my tranny replaced, they used 9 liters of fluid to fill it back up again.

It is not a very big job. It just can be a little messy if you are not careful. If you are lucky, you won't even loose a quart of fluid. Get something clean to catch the fluid in that does fall. Judge what to put back in from that.

Hope this helped you man.

 

You should lose about a pint or so of ATF when disconnectiong the tranny cooler lines. Make sure you check the level when you bolt them back up. You should be ok without having to flush out the tranny. Unless you have a tranny flush machine, I wouldn't recomment flushing it out.
